You're welcome!

The old problem was the infamous acoustic noise reduction setting.  Here I 
think the onlly change needed was to modify the default value of the 
firmware setting, which could also have been done with hdparm.

The new problem seems to be related to the SMART auto offline test which 
the drive periodically runs to update its SMART data.  But this is just an 
educated guess based on what WDC has written in their FAQ.
